Abstract

L'invention concerne un procédé d'attribution dynamique d'une commande d'une mémoire (115). Le procédé décrit dans cette invention consiste à recevoir une demande d'accès envoyée par un premier ordinateur (110) qui sollicite l'accès à une mémoire (115); à commander, en fonction de la demande d'accès, à un premier ordinateur de contrôle de mémoire (130) d'adopter un état inactif par rapport à la commande de la mémoire (115); puis à commander, en fonction de la demande d'accès, à un second ordinateur de contrôle de mémoire (130) d'adopter un état actif par rapport à la commande de la mémoire.
